A Case-Control Study of Respiratory Cancer and Employment.
NIOSH 1984 Apr:85 pages
A multiple logistic risk analysis procedure was used to compare data from 346 case/control pairs to determine occupational/industrial risk factors for respiratory cancer. The duration of employment was considered in blue collar production occupations. Five industrial categories were included: shipyard, petrochemical, metal related, construction and a grouping of other occupations under a single heading. The bulk of this grouped category was made up of blue collar employees in the industries of transportation, food production, wholesale and retail trade, professional services and public administration. Specific attention was given to asbestos (1332214) exposure, cigarette smoking, educational level attained, and dietary factors such as consumption of vegetables, fruits, and alcohol. A moderately elevated risk for respiratory cancer existed among employees in the metal industry and grouped categories when employment was over 30 years duration. In the metal industry this increase was almost entirely due to a larger than expected number of cases of larynx cancer. Lack of a significantly increased risk among shipyard workers differs from an earlier study in this area. With the exception of asbestos and the tar, soot and carbon black category, few exposures to specific substances identified as respiratory carcinogens were reported. A negative association of green vegetable consumption with respiratory cancer risk was consistent with evidence on protective effects of foods high in beta- carotene.
